13 Claims. (Cl. 88--24) Specifically it is an object of the present invention to provide an improved stock quotation projecting machine having a single projector,

one or more screens in the same plane, two printers one standard and the other of reverse construction, and two tape pullers whereby the messages or quotations of two diiierent printers or tickers transmitting different messages or quotations may be simultaneously projected as quickly with one as with the other.

' It is still another object of the present invention to provide an improved stock quotation projecting machine having a single optical system provided with one or two light apertures in the same plane and one or two screens in the same plane, two printers one standard and the other of reverse construction, and two tape pullers,

' in which the tape discharge ends of the printers are equally spaced from the entrance ends of the light apertures when two apertures are provided or from the common entrance end of a single light aperture when only one light aperture is provided.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific em-' bodiment thereof illustrated in the accompanying drawings in which Figure 1 is a plan more or less diagrammatically showing two tickers and a single projector constructed according to the present invention;

Fig. 2 is an enlarged fragmental plan showing a portion of a condenser and portions of the tapes of two tickers crossing the same; and

Fig. 3 is an end elevation partly in section showing the relative position of the projector,'

I The tape 9 is discharged by the ticker l1 in'the which the rays are directed upwardly to and through the condenser 8 supported in the upper end of the extension 1 across which the two tapes 9 and I pass and from which the images produced of the markings on the tape are directed upwardly through the objective lens unit mounted in the casing H by which the same are directed upwardly onto the reflector or mirror t2, then onto the reflector or mirror l3 and finally onto the rear faces of the translucent screen portions 10 M and I5 of the screen member 16.

As will clearly appear from Fig. 3, the light rays of the two tapes will converge in the lens unit mounted in the casing H and again diverge into two separate independent light beams striking the mirrors i2 and I3 and screenportions l4 and i5, defined by the areas A and A of the mirrors l2 and i3 respectively and the screen portion it for the'images of the tape 9 and defined by the areas B and B on the mirrors i2 and i3 respectively and the screen portion l5 for theimages of the tape H].

It will also appear from the foregoing that the .dimensions of the ultimate images on the screen portions l4 and l 5 must obviously be substantially identical if the dimensions of the characters on the tapes 9 and ID are substantially identical since the optical. system is practically common for the images-oi both tapes except that different portions of practically the same light apertures are used formed by the condenser 8 and that different portions of the same mirrors I2, 13 and.

vscreen member it are used for the images of both tapes. a 1

The tapes 9 and III) are discharged by the printers i1 and i8 respectively. The printer I! is of standard construction and for the purpose of this description will be designated as the right hand ticker or printer. The printer l8 will be substantially identical to the printer I! in con-'- struction except that it will be constructed the very reverse of the printer l1 and therefore for the purpose ofthis description will be referred to as the left hand ticker.

'It is of course obvious that the ticker I8 may also be constructed substantially identical to the ticker l1 except that its tape discharge end is formed on the reverse side to that on which the tape discharge end of the ticker H is formed.

usual way and is caused to be drawn or pulled across the condenser 8 by a standard tape puller, such for instance as the tape pulling roller l9, drivingly connected with the motor 20, the circuit of which motor 20 is controlled by a switch formed in the housing 2| having the lever 22 with a finger 23 on its free end to engage the tape 9 between the ticker and the light aperture in the usual way so as to respond to deflections in the tape and thereby establish or cut off the current to the motor 20 according to the operation or non-operation of the ticker l1.

The tape I0 is similarly caused to be drawn or pulled across the light aperture or condenser 8 as it is discharged by the ticker Hi, this tape pulling mechanism being substantially identical to the tape pulling mechanism for the ticker I1 and consisting essentially of a tape pulling roller 24 drivingly connected to the motor 25, the electric conductors of which are connected to the switch formed in the housing 26 having the lever 21 with a finger 28 on the free end thereof riding on the tape 10 between the ticker l8 and the condenser 8 to respond to deflections in the tape to establish or cut off the current to the motor 25 according to the operation or non-operation of the ticker l8.

From the foregoing, it will be seen that by this arrangement of ticker construction, a single optical system can be used consisting of a single source of light, a common light aperture, a common screen member except that different portions of the common light aperture will be used by the two different tapes and similarly that two different portions of the common screen member will be used for the images of the two different tapes.

In this way, it will also appear that if the tickers are equally spaced from the condenser 8 or light apertures formed by or above the same and the dimensions of the markings on the tape are substantially identical that the ultimate images on the screen will be substantially identical.

It will also appear that by this construction, the interval of time required for an image to appear on the screen member l6 for a character produced on the tape 9 will be substantially equal to that required for producing an image on the screen member l6 of a character produced on the tape [0.

Note should also be taken of the fact that negative type characters may be used on the type wheels of both tickers to produce positive impressions and that in at least this respect the printer l8 need not be the reverse of the printer l1, and that in turn positive type characters on the type wheels of the printers may be used when, as an instance, it is desirable to use a single mirror adjacent the screen, instead of two mirrors, such as the mirrors l2 and I3.

It is also obvious that the present system lends itself admirably for use where it is desirable to have the quotations from two tickers exhibited adjacent to one another. As an instance, a demand has risen for tickers rendering so-called express service, that is transmitting only the quotations of a few so-called leaders or only the quotations of the sales of a stock exceeding a certain predetermined volume. With the present system, one of the tickers may transmit the quotations now customary and the other ticker render such express service.

On the other hand, those brokers who wish to cater to the trader of commodities listed on exchanges, such for instance as the curb exchange, produce exchange or the like, other than on the New York Stock Exchange may wish to have the quotations from two of such exchanges transmitted adjacent to one another so that traders of the commodities on at least two such exchanges may conveniently have both reports transmitted adjacent to one another. The present system is uniquely adapted to fill the latter need. V

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
